Quad Core processor? I have 2 year old PC from Alienware, and the motherboard that came with the system is an AA8XE board from ABIT. It has a "uGuru" symbol all over it, I don't know what that is. I've been systematically upgrading it over the past few months. New RAM, new hard drive, new sound card, and an 8800GTS (a week before the 8800GT was revealed, ugh).The PC has a 3.0 ghz processor, and bottlenecks my graphics card. I've decided that I need a new processor. I want to get either an E6600 or a Q6600. Both these have the same FSB (1066) and the same slot interface (LGA 775).I am just wary of buying the new technology because I don't know if the new technology is compatible with the old motherboard.
